According to the ITF website, Luka was born in Umag, resides in Kopar and is just 19 years old (born in October 1988). He had some success as a junior, reaching the Wimbledon QF and US Open SF in 2006, then turned pro in 2007. Here are his year-end pro rankings:

End of 2005: 1497
End of 2006: 1036
End of 2007: 763

In 2008, he had been moving sideways in the rankings until this week. This win, though, will give him a new career-high ranking of around 680--and hopefully lots of confidence.
